Defining vacuum - SCROLLVAC plus, Leybold's new dry scroll pump.

The new SCROLLVAC plus vacuum pump is the latest addition to our dry pump series. SCROLLVAC plus offers a flexible, robust and simple vacuum pump solution for a wide range of applications, demonstrating the potential of dry scroll pumps.

Vacuum pumping principle

A scroll pump consists of two intermeshing scroll forms. One scroll is mounted eccentrically on the other and moves it in an orbit relative to the fixed scroll. This creates crescent-shaped volumes that are driven from the outside to the inside, thereby pumping gas.

Able to handle the widest range of applications...

Flexible.

We understand that flexibility and choice are essential when selecting the right dry vacuum solution for your application. With single-phase and three-phase variants and versions for special applications, you are sure to find the SCROLLVAC plus series member that suits you.

Pump versions cover 7, 10, 15 and 18 m³ /h pumping speed

Single-phase variants feature a universal voltage drive for constant performance worldwide

Three-phase non-electronic variants for radiation and high magnetic field applications

Integrated gas ballast enables pumping of condensable vapors

The compact, lightweight design allows easy integration into your new or existing vacuum system

Ready to withstand and overcome demanding conditions……

Robust.

SCROLLVAC plus is designed to maintain performance and reliability in the most demanding applications. With the bearings completely separated from the pumping mechanism, you can ensure zero contamination within the vacuum envelope and excellent vapor handling capability.

A true dry vacuum pump with pump bearings isolated from the vacuum space, eliminating any risk of contamination

No shaft seal wear, extending service intervals and improving sealing performance

The ideal dry pump solution for backing turbomolecular pumps and cryopumps

The optional C variant is available for certain applications involving pumping corrosive media and chemicals

Easy to understand and straightforward……

Simple.

Not only are servicing and end seal replacement simple and quick, but long service intervals mean SCROLLVAC plus can be a “fit-and-forget” solution. 

The latest tip seal technology significantly extends the interval between tip seal replacements, typically to 2.5 years, maximizing uptime and productivity

Easy maintenance with typical tip seals replaceable in 10 minutes

Run-time counter as standard

Save costs by switching to the latest technology……

Environment.

Think the environment is too big to make an impact? We are constantly looking at ways to reduce environmental impact, and choosing the latest SCROLLVAC plus can immediately improve your local workspace.

No contaminated waste oil to handle, and no expensive disposal or waste oil recycling

< 55 dB(A) low noise, suitable for quiet working/laboratory environments

Lower power consumption compared with other pumping mechanisms

Reliable product and application expertise……

Leybold, guaranteed at all times!

SCROLLVAC plus is designed for a wide range of applications, from general laboratory, light industrial and research to more aggressive chemical applications, making it easy to choose the right dry vacuum pump.

Physics research

Dry compression pump——zero risk of system contamination

Excellent ultimate pressure of the turbomolecular pump

High water vapor capacity for cryopump regeneration

Low noise for a quiet working environment

Three-phase pump without electronics, suitable for radiation areas

Long maintenance intervals and easy end-user maintenance

Industries

Robust pump with high vapor capacity for industrial applications including vacuum ovens, degassing and sterilization. Also suitable for cyclic tasks

No exposed bearings or shaft seals, ensuring reliable operation in numerous industrial applications

Multiple pumping performance options to meet all requirements

Wet chemistry

Quiet, reliable operation for biological and wet chemistry laboratories

High water vapor capacity for applications such as gel drying, centrifugal concentrators, rotary evaporators and solvent recovery

Pump chamber and rotating parts are hermetically isolated, so the pumped gas does not react with the lubricant

The C version is suitable for more corrosive gases

Gas recovery

High tightness ensures no gas contamination or loss in gas recovery applications

Excellent helium pumping performance

The C version is ready to withstand harsh conditions.

SCROLLVAC C plus variants are designed for more aggressive applications where potential degradation of internal parts due to corrosion must be considered. Combined with a suitable purge gas flow, this means SCROLLVAC C plus models can be configured to handle corrosive solvents and chemicals:

Chemical-resistant exhaust check valve and gas ballast valve

Stainless steel inlet and exhaust flanges

Conversion kit available to allow customers to upgrade their standard variant
